Many device manufacturers point out that their applications only work with 1.5V alkaline batteries and warn against the use of NiMH batteries whose voltage is too low at 1.2V for proper function. With nickel-zinc batteries with a voltage of 1.6V per cell, such devices can be operated without any hesitation. This saves the constant purchase of disposable batteries and relieves the environment and the wallet.ANSMANN offers a charger with nickel-zinc charger, which is specially designed for the requirements of these batteries. With the new NiZn charger, up to four NiZn batteries of the sizes Micro AA and/or Mignon AAA can be charged, even mixed. The battery charge level before the start of charging is irrelevant. Defective NiZn rechargeable batteries and NiMH/NiCd rechargeable batteries inserted the wrong way round are automatically detected and not charged. Each battery bay is monitored separately so that the batteries can be charged individually and independantly with a charging current
